Portable heat circulation means

DETAILED DESCRIPTION The present invention provides a portable heat circulation device which is particularly adapted to be usable when placed upon the top of a heater such as a kerosene heater or the like to gather and distribute the air therefrom in a more even manner throughout the room to be warmed.
The circulation means includes a plenum housing which is adapted to be directly placed on top of the kerosene heater.
This plenum housing defines a plenum chamber therein which is adapted to gather the heated air provided from the heater.
This heated air is introduced into the plenum chamber through a plenum intake means which is an open area in the bottom surface of the plenum housing.
A plenum wall extends around the plenum chamber and defines therein a number of hot air apertures which allow the flow of heated air from the plenum chamber into the surrounding environment.
The upper boundary of the plenum chamber is defined by a plenum top means which extends over the plenum wall means.
This plenum top means is generally of the convex configuration facing in an upward direction.
In this manner an arcuate surface is provided as the top wall of the plenum chamber.
In this manner this surface is heated and when cool air is caused to pass thereover, a means of circulation of warm air is provided.
A main housing means is fixedly secured to the plenum housing means preferably by way of a plurality of legs extending therebetween.
The bottom surface of the main housing means includes a main outlet means such that cool air can be expelled outwardly therethrough.
This main outlet means is positioned adjacent to the convection surface such that it can travel along the convection surface and pick up the heat therefrom for dissemination into the surrounding environment.
The lower end of the main housing means and the upper portion of the plenum housing means defines a main outlet means therebetween such that air after it has traveled through the cool air outlet and been warmed by passing adjacent to the convection surface can pass outwardly into the surrounding environment for heating thereof
